Thanks all for your recommendation!

I was just curious?   Any members try the duelund foil 1.0, 2.0 or 3.0 flat silver wires?  Can it be use as main speaker wires?? Please advise?? 
Grannyring... on main speaker cables, each channel single run of the 16ga stranded tinned copper or you recommend 3 runs per channel.  
I need 12ft long from amp to speaker.  What is your suggestion??
